You just love them cans o' worms, don't ya? Kinds of paints is even more debated than types of sealers/fillers! The only more discussed/debated subject is adhesives/glues, so you might want to be careful before you complete the hat trick.
I personally use Krylon, but others swear by Rustoleum paints, Testors or Tamiya model paints. Some use the local hardware store brands. Some use acrylics, some use enamels, some use spray epoxy paints.
The most important things to remember are to take your time, use light coats, and test your paints on a scrap of wood before combining them!
Also, you can find a paint interaction matrix on EMRR that will give you a pretty good guide for what paints mix with others.
